Windows 8's server counterpart, Windows Server 2012, is in development concurrently with Windows 8.
According to the Windows Design Team, Windows 8 has been "reimagined from the chipset to the user experience, whereas Windows 7 was intended to be a more focused, incremental upgrade to the Windows line. Windows 8 features a new user
interface based on Microsoft's Metro design language, similar to that in Windows Phone. Microsoft claims the new interface is designed to better suit touchscreen input, along with traditional mouse and keyboard input. A version of Windows 8, called Windows RT, also adds support for the ARM processor architecture in addition to the previously supported x86 microprocessors from Intel, AMD, and VIA.
